The music is generated completely and exclusively from the voices of Crystal Dreams and Pixyblink by Jack Hertz:
My original idea of trying to do a choral type piece didn't work well at all. So, I started playing around with the phase distortion tricks Steve Reich used on the "Come Out" album. That gave me the idea to do an abstract terrain kind of piece instead.
I used all the Caterpillar sound files, nothing else. Each file was looped wholesale, duplicated and stretched a bit to create a phased distortion track. Next, I did a lot of processing with Lexicon and N2O effects on each of the tracks. The final piece is all of the 14 samples offset and layered together to build a long drone scape.
The Caterpillar and Alice looked at each other for some time in silence: at last the Caterpillar took the hookah out of its mouth, and addressed her in a languid, sleepy voice.
'Who are you?' said the Caterpillar.
This was not an encouraging opening for a conversation. Alice replied, rather shyly, 'I — I hardly know, sir, just at present — at least I know who I was when I got up this morning, but I think I must have been changed several times since then.'
'What do you mean by that?' said the Caterpillar sternly. 'Explain yourself!'
'I can't explain myself, I'm afraid, sir' said Alice, 'because I'm not myself, you see.'
'I don't see,' said the Caterpillar.
'I'm afraid I can't put it more clearly,' Alice replied very politely, 'for I can't understand it myself to begin with; and being so many different sizes in a day is very confusing.'
-Lewis Carroll, Alice's Adventures in Wonderland (1865)
